Spiral welding can be used in the remanufacturing process to repair and improve products. Improvements can be made to the component through this process by using a selection of advanced overlay materials; this is based on two broad criteria: [1] A match of the parent material with a filler wire of the same or closest available selection material.
In 2000, American opened American SpiralWeld Pipe Company in Columbia, South Carolina, diversifying its product line to include spiral-welded steel pipe in diameters up to 144 inches (3,700 mm). In 2015, American began operations at a new spiral-welded pipe production facility in Flint, Michigan. A third facility opened in Paris, Texas, in 2021.
Pipe welding is often performed by specially licensed workers whose skills are retested periodically. For critical applications, every joint is tested with nondestructive methods. Because of the skills required, welded pipe joints are usually restricted to high-performance applications such as shipbuilding, and in chemical and nuclear reactors.
Welspun Tubular LLC (USA): This spiral pipe and coating facility is spread across 740 acres and has an annual capacity of 350,000 tons near Little Rock Port, Arkansas. Welspun Tubular LLC begins production at its new electric-resistance welded (ERW) steel pipe mill in Little Rock, Ark., in 2012 according to a company executive. [33]
The most common process pipe joint is the butt weld. The ends of pipe to be welded must have a certain weld preparation called an End Weld Prep (EWP) which is typically at an angle of 37.5 degrees to accommodate the filler weld metal. The most common pipe thread in North America is the National Pipe Thread (NPT) or the Dryseal (NPTF
Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels, floors, roofs, and piles.

This type of mesh is a square grid of uniformly placed wires, welded at all intersections, and meeting the requirements of ASTM A185 and A497 or other standards. [1] The sizes are specified by combining the spacing, in inches or mm, and the wire cross section area in hundredths of square inches or mm2.
